Data Transmission Considerations

What is the main impact of bandwidth and latency on a business with international links?

• Bandwidth and latency affect the cost and efficiency of data transfer
• Bandwidth and latency have no impact on international links
• Bandwidth and latency increase security in international links
• Bandwidth and latency decrease the need for encryption in international links

What is the role of a codec in data compression?

• Compressing data only
• Encrypting data for security
• Compressing and decompressing data
• Decompressing data only

What is the main factor affecting the time delay for data packet transfer?

• Wired connection speed
• Type of wire cabling
• Volume of data being transmitted
• Distance to nearest exchange

What is the main purpose of compression?

• Deleting data to save space
• Encrypting data for security
• Increasing file size for better quality
• Reducing file size for faster transfer

Why does online gaming need very low latency?

• Players need to compress data for faster transfer
• Players need a fast response for real-time updates
• Players need high bandwidth for large file transfers
• Players need encrypted connections for security

What type of wire cabling is inherently more secure for data transmission?

• Fibre
• Coaxial
• Twisted pair
• Ethernet

What is the relationship between bandwidth and latency in data transfer?

• Latency affects the speed of data transfer, while bandwidth affects the delay
• Bandwidth affects the speed of data transfer, while latency affects the delay
• Bandwidth and latency are the same thing
• Bandwidth and latency have no impact on data transfer

What is the main purpose of user authentication in network security?

• To increase latency in data transfer
• To monitor traffic for dangerous data packets
• To compress data for faster transfer
• To prevent unauthorized access by hackers

What is the main purpose of encryption in secure data transmission?

• To compress data for faster transfer
• To maximize available bandwidth
• To increase latency in data transfer
• To ensure intercepted data cannot be read

In a business with international links, why is it important to choose the right time for data transfer?

• To avoid high latency
• To maximize available bandwidth
• To increase the risk of data loss
• To minimize the need for encryption
